Recenlty my battery life has decreased significantly, dropping to 50% in 4 hours of very little use. I don't see any new or unsual services or apps running, so I'm thinking it may be time to replace the battery. I'm using the Motorola extended battery (BH6X) and it is only about 8 months old. This seems like a pretty short lifespan for a battery. I'm wondering how frequently others are finding they need to replace a battery. Thanks.
